A warm front will move through the region Sunday night into early Monday morning, warming temperatures through the overnight hours. Snow showers are possible as the front moves through, especially over the southern Black Hills. Accumulations will range from a dusting to an inch.
As the warmer air slides in, Monday will turn out to be a relatively mild day. Temperatures in the highest elevations of the Black Hills will surge into the mid 40s. Upper 30s and lower 40s are expected most everywhere else. To the north, the cold air will linger, with highs only in the teens in the far northern part of the viewing area.
There will be up and down temperatures throughout the week. Monday will likely be the biggest up. Things will start to cool down for Tuesday, with highs in the 20s.
By Wednesday afternoon and evening, our next chance of another real measurable snowfall will arrive. Models point at anywhere from 1-3 inches through the area. I believe that will be closer to 1 than 3. However, it is still several days out, and the track of the system could certainly change.
